How are teeth like eggs?
The shell of an egg behaves kind of like a tooth. So, both Kindy classes did an experiment to see the effect of soft drink on an egg/tooth.
One egg sat in a popular brand of cola for a day, the control egg sat in water so we could compare what happened.
When the eggs came out, the cola egg was brown and slimy but the other egg was still clean.
We know when teeth need to be cleaned, so we thought we should clean the egg. A dry toothbrush didn’t work. A wet brush didn’t work. Only a wet toothbrush with toothpaste helped, and only if we kept scrubbing long enough (singing the alphabet song once or twice in your head offs a good guide). This is the yucky egg after half of it was cleaned.
One person wondered if it the inside of the egg would change colour like the shell changed colour. We opened the egg tho find out but it was still egg coloured inside!

The Germ Experiment
AIM: How do germs get into you and on to other people?
METHOD:
- Mrs Klose put glitter on her hands. She put her hands on things and the glitter germs went on the things. When someone touched the things with glitter germs on them, the glitter germs went on the person! Then the person touched things and the glitter germs kept moving.
- We had to get rid of the glitter germs. we tried: paper towels and tissues, then water on its own, then water with soap, and scrubbing, and then some hand-wash from a bottle. Water and soap and scrubbing was the best at getting rid of glitter germs!
Glitter Germs
Today we used glitter to demonstrate how quickly and easily germs can spread. Some people got different colours of glitter put on their hands. Then, we did ordinary things like shaking hands, moving around the room, playing games, sharing equipment, and normal bookwork at our desks. At first we thought it was funny how the glitter spread around! Then when we realised that’s what germs do too, we understood how important it is to be clean, wash hands properly with soap, and to stay home when you’re sick.
Question: Where do germs come from?
Germs are actually living things found all over the world. There are 4 types of germs: bacteria, viruses, fungi, and protozoa. Because they are so tiny, they can get inside our bodies and make us sick. But what exactly can they do?
- Bacteria: They can reproduce inside or outside the body. Some infections bacteria cause include sore throats, ear infections, tooth cavities, chest infections, and pneumonia.
- Virus: They can only live for long while inside a living thing and take nutrients from bigger living things. Some diseases viruses caused: chickenpox, measles, the flu, and many other diseases. Because some viruses can live for a while on something like a doorknob or countertop, be sure to wash your hands regularly!
- Fungi: These are plant-like living things that love warm, damp places and take nutrients from bigger living things. They often cause itchy skin rashes like tinea (athlete’s foot) and ringworm.
- Protozoa: These organisms love moisture and spread disease through unclean water. They can cause tummy problems like nausea (feeling like you need to be sick), belly pain and diarrhea.
If you do get sick, a doctor can look at what’s wrong with you, and look at your blood in a laboratory to see what is making you sick and figure out how to make you better.
The good thing about all these yucky germs is that we can protect ourselves really easily. Wash regularly with soap and water (especially after doing anything dirty, and before eating), and then dry yourself thoroughly. Always cover your mouth when you cough or sneeze and throw the germ-covered tissues away. Then look after your body with food and exercise so it has the best chance of fighting off any germs.
By the way, did you know there are even a few bacteria that are good for our bodies? They live in our bellies and help digest food!
Weekly Wonderful Website: T3W3
We are more than halfway through Winter now! You may have noticed that in Winter, lots of people get sick with a cold or the flu. So we need to be smart to make sure we don’t make each other sick! The website www.sneezesafe.com.au has some good tips to stay healthy. They suggest a 3 step procedure:
- Catch it (Use a tissue!)
- Bin it (Throw away your germ-covered tissue)
- Kill it (Wash your hands thoroughly with soap)
Go to the site and watch the videos or play the games to learn more about being ‘sneeze safe’!
